So. You've just made a game. It gets on trending. Then, a few days later, a new game arrives. Different code, but it's the exact same art! And then they don't give credit. What do you do to stop that? Well, it is easy. Since you cannot just select things and remove them in bitmap, if you have made it in vector, set it to bitmap, and then when in bitmap, use the text tool to write your username. Just put it in a corner where it is not noticeable, and put it down. Now, if another project uses that art, you can comment "How is it your art, if it is signed by me?"
